But this hack, is not solution.
I checked other look-like code, everywhere when summary width of bottom columns greater then top columns, we get same bug.
May be once at table creattion when column width undefined - calc autosize?
var tmp = $('<div/>').css({display:'inline',visibility:'hidden'}).text('Restructured outdated').appendTo('body');
var autoSize = tmp.width();
tmp.remove();k
